Title: Cipher key management equipment
Inventor: MIYAUCHI HIROSHI
IPC: H04L9/32
Filed: 1995-01-30
Abstract: PURPOSE: To allow a center to conduct cipher communication with a terminal equipment and verification of the terminal equipment without having a cipher information list by writing an ID of a terminal equipment and cipher information in advance to the terminal equipment and to cipher data again and to obtain the cipher information at communication and to allow the center and the terminal equipment to use the cipher information in common. CONSTITUTION: A center 300 keeps ciphering information Kc . The center 300 calculates terminal equipment cipher information Si = Encipher (Kc .IDi ) based on the IDi of the terminal equipment to initialize the terminal equipment 360. The center 300 writes the IDi and the Si to the terminal equipment 360. At the start of cipher communication, an ID information storage device 391 of the terminal equipment 360 at first sends the IDi to a network interface(IF) 380, the IF 380 sends the IDi to a center 300 through a network 350. A terminal cipher information holding equipment sends information Si to a key storage device 393. The center 300 receives the IDi and gives it to a converter 320. The converter 320 receiving information Kc from a storage device 321 calculates the information Si and stores it to a storage device 322.  Thus, the center 300 and the terminal equipment 360 use the information Si in common to allow the center 300 and the terminal equipment 360 to conduct cipher communication.

Title: Magneto-resistance effect element
Inventor: NOMURA AKIHIKO
IPC: H01F10/08
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain a large resistance changing rate, a superior sensitivity and a large output by providing a first ferromagnetic film having a laminating structure of a ferromagnetic film and a nonmagnetic film and making the magnetization direction of the ferromagnetic film to be arranged in a antiferromagnetic aligning manner by mutal action. SOLUTION: A ferromagnetic film 23 and a nonmagnetic film 24 are alternatively laminated. For example, if they are laminated in four layers, the top surface is the film 24 and the film 23 is laminated at the joint surface with a nonmagnetic intermediate layer 25 in order to produce a nonmagnetic/ ferromagnetic boundary surface. Since the magnetization directions of the ferromagnetic films are reversed for every layer, the electrons having either spin directions are not able to pass the films, which are magnetized in the reversed directions of the spin, scattered and thus, the resistance becomes larger. In order words, electrons are scattered at the boundary surfaces of a first ferromagnetic film 22 and a second ferromagnetic film 26. In addition, a scattering occurs in the film 22 and the two operations are superimposed and a larger resistance variation is generated.

Filed: 1985-01-29
Abstract: PURPOSE:To obtain a fluorine-containing copolymer which can be formed into a paint of good storage stability by a simple process, by copolymerizing a fluoroolefin with an alkyl vinyl ether in the presence of an alkali metal carbonate in a lower alkyl-substituted benzene as a polymerization medium. CONSTITUTION:A medium comprising a lower alklyl-substituted benzene and at least one component having as b.p. lower than that of said benzene, selected from among a 2-4C linear or branched alkanol, dioxane, monoglyme, acetonitrile and water is used as the polymerization medium. A fluoroolefin is copolymerized with an alkyl vinyl ether in the presence of an alkali metal carbonate (preferably, potassium carbonate) and a radical initiator in the above medium. Examples of said benzene include toluene, xylene and isopropylbenzene. By using the polymerization medium containing the lower alkyl-substituted benzene, it is possible to simplify a process for forming the copolymer into a paint because the copolymer need not be separated from the polymerization medium when it is formed into a paint.

IPC: B23D47/08
Filed: 1993-01-29
Abstract: PURPOSE:To obliterate useless movement of a saw after the completion of sawing when a structural angle placed on a table is cut off by the saw, by detecting the completion of sawing through the cutting sound of the saw.

Title: Ignition timing control device for internal-combustion engine
Inventor: HASE YOSHIFUMI
IPC: F02P5/155
Filed: 1982-01-30
Abstract: PURPOSE:To prevent knocking by an arrangement wherein the shift of a transmission gear to a predetermined position is detected and the ignition timing is delayed for a fixed period of time. CONSTITUTION:In case an engine 1 provided, for example, with a four-stage transmission gear is accelerated under side gear or top gear condition or under high gear condition, a gear switch detects the position of the high gear and is closed. A load switch 48 detects the increase in the load and is closed, and as a result, a three-way solenoid valve 42 is energized to supply a negative pressure to an ignition angle delaying vacuum chamber 33. Therefore, the ignition timing of the engine 1 is delayed thereby preventing knocking of the engine 1.

Accordingly, a double flange 20 is prevented from deforming against the insertion force when the engaging part 26b of an inner box 26 is inserted into an inner box insertion slot 24. The periphery of the heat sink pipe 27 in the pipe slot 25 is cured by the hotmelt 28 to integrate the double flange 20 with the heat sink pipe 27, thereby raising the strengths of an outer box 15 and an adiabatic box 16. The heat sink pipe 27 is brought into direct contact with the outer box 15, and heat is conducted to the outer box 15 via the hotmelt 28. Thus, quantity of heat sink to the atmosphere is increased, and the quantity of heat invaded from the inner box flange into the box is reversely reduced.
